| * before... it was buried within the compare() method at |
| * https://code.google.com/p/skia/source/browse/trunk/gm/gmmain.cpp?r=7289#305 . |
| * |
| * Apparently we need this, at least for bitmaps that are either: |
| * (a) destined to be written out as PNG files, or |
| * (b) compared against bitmaps read in from PNG files |
| * for the reasons described just above the force_all_opaque() method. |
| * |
| * Neglecting to do this led to the difficult-to-diagnose |
| * http://code.google.com/p/skia/issues/detail?id=1079 ('gm generating |
| * spurious pixel_error messages as of r7258') |
| * |
| * TODO(epoger): Come up with a better solution that allows us to |
| * compare full pixel data, including alpha channel, while still being |
| * robust in the face of transformations to/from PNG files. |
| * Options include: |
| * |
| * 1. Continue to call force_all_opaque(), but ONLY for bitmaps that |
| * will be written to, or compared against, PNG files. |
| * PRO: Preserve/compare alpha channel info for the non-PNG cases |
| * (comparing different renderModes in-memory) |
| * CON: The bitmaps (and checksums) for these non-PNG cases would be |
| * different than those for the PNG-compared cases, and in the |
| * case of a failed renderMode comparison, how would we write the |
| * image to disk for examination? |
| * |
| * 2. Always compute image checksums from PNG format (either |
| * directly from the the bytes of a PNG file, or capturing the |
| * bytes we would have written to disk if we were writing the |
| * bitmap out as a PNG). |
| * PRO: I think this would allow us to never force opaque, and to |
| * the extent that alpha channel data can be preserved in a PNG |
| * file, we could observe it. |
| * CON: If we read a bitmap from disk, we need to take its checksum |
| * from the source PNG (we can't compute it from the bitmap we |
| * read out of the PNG, because we will have already premultiplied |
| * the alpha). |
| * CON: Seems wasteful to convert a bitmap to PNG format just to take |
| * its checksum. (Although we're wasting lots of effort already |
| * calling force_all_opaque().) |
| * |
| * 3. Make the alpha premultiply/unpremultiply routines 100% consistent, |
| * so we can transform images back and forth without fear of off-by-one |
| * errors. |
| * CON: Math is hard. |
| * |
| * 4. Perform a "close enough" comparison of bitmaps (+/- 1 bit in each |
| * channel), rather than demanding absolute equality. |
| * CON: Can't do this with checksums. |
